How to set DataChangeFilter in listener

[xshan8333]

Problem

• (X) bug report => please search github for a similar issue or PR before submitting

• ( ) unexpected behavior => please visit the Wiki before

  Current behavior

  I get Square1 data from Prosys simulation server. but get changed data only!

  Expected behavior

  I want DataChangeFilter=StatusValueTimestamp. How can i set it?

  Minimal reproduction of the problem with instructions

  1.inject is { "interval": 1000, "queueSize": 1}

  2. Prosys sim server log is: ItemsToCreate=MonitoredItemCreateRequest[1] [0]=MonitoredItemCreateRequest ItemToMonitor=ReadValueId NodeId=ns=5;s=Square1 AttributeId=13 IndexRange=null DataEncoding=null MonitoringMode=MonitoringMode name=Reporting ordinal=2 RequestedParameters=MonitoringParameters ClientHandle=2 SamplingInterval=1000.0 Filter=null QueueSize=1 DiscardOldest=true

Hi,

• was it working in the versions before? (you set bug report, not unexpected behaviour)
• is it node-opcua v0.4.6 in the global install?
• could you build some example to get it to work with node-opcua 0.4.6?

• options.trigger {DataChangeTrigger} {Status|StatusValue|StatusValueTimestamp}
  • options.deadbandType {DeadbandType} {None|Absolute|Percent}
  • options.deadbandValue {Double}

Hi, biancode: I just study OPC UA with node-red. be prepare for access some PLC device. I use node-red-contrib-iiot-opcua for first time now, so i need some help. sorry set bug report, but i donot known how to set "DataChangeTrigger ..." options in node-red. next is my flow in node-red. maybe give me some advice? thanks.

it works as expected via listener parameters

{ "interval": 200, "queueSize": 10, "options": { "requestedPublishingInterval": 1000, "requestedLifetimeCount": 1000, "requestedMaxKeepAliveCount": 12, "maxNotificationsPerPublish": 100, "publishingEnabled": true, "priority": 6, "trigger": "StatusValueTimestamp" } }

That is to set from your first inject to the listener. It does not change with next option injects without a deploy before.
